SHEET 30F 3' INVENTOR. ALFRED J. DEPA T/E BY EL WYN P. HART A ctornczg/ s ARCHERY BOW WITH SIGI-ITING MECHANISM BACKGROUND OF INVENTION This invention relates to'an archery sighting apparatus and particularly to a hand manipulated archery bow having an improved optical sighting device for aiming and controlling the projectory of the arrow.

The archery bow is traditionally fired by the archer sighting along the length of the arrow and directing the arrowhead in predetermined relationship with respect to the target before releasing of the arrow. The desired alignment is normally controlled by the manual skill and dexterity of the archer which are, of course, only developed with experience. If the arrow falls short or long, the archer adjusts the sighting by realigning the head of the subsequent arrow with a properly spaced point with regard to the target. Thus, the accuracy is essentially fully controlled by the archers skill and furthermore is dependent upon maintaining the same fixed or selected positional relationship between the bow, arrow and the archer at all times and for successive shots in order-to properly aim the arrow.

SUMMARY OF INVENTION The present invention is particularly directed to a mechanical archers sight mounted on the bow and providing an improvedsighting means which permits accurate and repeatable projectory of an arrow with a very minimum amount of skill.

Generally, in accordance with the present invention, a sight means preferably having adjustment means for windage and elevation compensation is mounted to the bow by suitable support means which locate an eye sighting portion of a telescopic construction immediately adjacent to the shooter's eye with the arrow and string drawn back preparatory to actual shooting. The mounting means is in an optimum construction adjustably mounted to permit readjustment of the position of sight means relative to the bow to compensate for shorter and longer draw pulls. Further, the sight means in accordance with a further significant feature of the present invention is provided with a suitable locating means for positioning of the adjacent sight means with respect to the operator or archer to permit accurate location and support of the bow with respect to the archers eye. The sight means further includes a means to establish an accurate reference point to which the bow string and arrow is drawn each time. The result will be very accurate and repeatable projectory of the arrow with respect to the target. The present invention thus provides a relatively simple and reliable archery sighting means which can provide highly accurate and repeatable shooting by any archer of minimum skill.

DESCRIPTION OF ILLUSTRATED EMBODIMENT OF INVENTION bow immediately above and below the hand portion 3 and 4 locate the sighting unit 4 adjacent the eye 7 of the archer. The sighting unit 4 and its mounting particularly form the subject matter of the present invention and may be employed with any of the common hand operated bows.

The illustrated sighting unit 4 includes a telescopic sight 8 which may be of any known or desired construction which is adapted to be placed immediately adjacent to the archers eye 7 for proper sighting of a remotely located target. For example, the telescopic sight may be of a variety manufactured and sold by Realist, Inc. of Menomonee Falls, Wisconsin and identified by the-name Apache."

The sight 8 is a tubular unit extending through a tubular mounting housing 9 which includes adjustable means for adjusting the position of the telescopic sight 8 for windage and elevational variations or conditions. The tubular housing is illustrated as a generally elongated rectangular housing 9 having horizontal. and vertical surfaces secured to and mounted by members 5 and 6 to locate the telescopic sight 8 adjacent the archer. 1 i

A mounting shaft or tube member 10 is flattened at one end and bolted or otherwise secured to the upper exterior surface of the housing 9. Tube member 10 projects forwardly toward the bow 1, generally in a horizontal plane. The outer end of the mounting tube 10 has an internal diameter generally corresponding to the outer diameter of the mouting rod 5. The rod 5 projects into the tube 10 and is releasable secured therein through a clamping nut 11 which threads onto the outer end of the tube 10. The outer end of the tube 10 is also slotted as at 12 such that the tightening of the nut 1 1 collapses the shaft or tube 10 onto the rod 5 to provide a relatively firm frictional engagement therebetween. The location of the telescopic sight 8 may be adjusted with respect to the bow 1 by releasing of the nut 11 from the tube 10, permitting relatively free-sliding movement between the rod 5 and tube 10. When the sight 8 is properly adjusted, the nut 11 is tightened onto the tube 10 providing the firm locked positioning thereof relative to the bowl.

The rod 5 projects forwardly therefrom to the bowl and is interconnected to the bowl by a similar clamping tube unit 13. Thus, the unit 13 includes a tubular mounting member 14 within which the outer end of the rod 5 is slidably disposed. A clamping nut 15 slides over the rod 5 and threads onto the end of the mounting tube member 14 to provide a similar releasable clamp. v 4

As most clearly shown in FIGS. 6 and 7, the mounting tube member 14 is secured to the bowl in upwardly spaced relation to the hand grip portion 3 as follows. A generally U- shaped clamp or clip 16 is welded or otherwise secured to the outer surface of the mounting tube adjacent its outermost end. The base of the clip 16 is spaced somewhat from the tube 14 and a mounting strap 17 is looped through the clip. The strap 17 is preferably a flexible metal band which is formed as flattened loop. The loop extends around the backside of bow 1 with the opposite ends looped about similar cross bars 18 and 19 in legs of similar L-shaped clamping brackets 20 and 21. The Lshaped mounting brackets are disposed to the front side of the bow 1 with adjacent clamping legs extending outwardly in parallel relationship. A clamping bolt 22 extends through an opening in the one bracket 20 and threads through a threaded opening in the opposite bracket 21 to allow tightening and release of the strap 17 about the bow. This supports the bow end of rod in selective fixed relation to the archer, with a corresponding desired positioning of the telescopic sight 8 at eye level. The sight 8 is further supported by rod 6.

The rod 6 has its outer end interconnected to the underside of the telescope housing by a releasable clamping tube unit 23 generally corresponding to the attachments -12, inclusive, for rod 5. The rod 6 extends, in the plane of the bow, outwardly toward the bow and then downwardly to a horizontal projection which is interconnected to the bow 1 by a releasable tube and nut clamp unit 24 similar to the unit 13-15. The sighting unit 4 may therefore be adjusted with respect to the bow l at the bow 1 or at the sighting unit 4.

In the preferred construction illustrated in the drawing, the

mounting tube forming a part of the underside mounting unit 23 includes an integral rearward extension 25 terminating in a depending end support pad 26. As viewed from the top in FIG. 2, the extension 25 is bent laterally outwardly to locate the locating pad 26 adjacent the head of the archer and permits accurate positioning of the telescopic sighting unit 4 with respect to the eye 7 of the archer. Applicants have found that with the location of the telescopic sight immediately adjacent the archers eye and particularly with the adjustable mounting thereof, the archer can accurately shoot an arrow with a very minimum amount of skill and practice. The head-locating support provides accurate and repeatable positioning of the arrow and the draw of the string 2 for successive shots and thereby permits consistent, repeatable projectory of the arrow.

As previously noted, the archer may re-adjust the position of the telescopic sight 8 for elevation and windage correction. As most clearly shown in FIGS. 3 and 4 the telescopic sight 8 is a tubular member projecting through the somewhat larger rectangular housing 9. The forward end of the housing is provided with a support plate 27 having an opening 28 generally corresponding to the diameter of the telescopic sight 8. The wall of the opening 28 is curved or rounded to permit both horizontal and vertical tilting of the telescopic sight 8 with respect to the closure or support plate 27. The plate 27 is preferably formed of a nylon or other similar material which allows pivotal movement of the telescopic sight 8 within the opening.

A windage slide plate 29 and an elevational slide plate 30 are slidably mounted in the opposite end of the housing 9 between an inner stop plate 31 and an outermost end plate 32. The stop plate 31 and end plate 32 are generally similar rectangular frame members releasably interconnected in axially spaced relation within the end of the housing 9 by suitable mounting screws or the like. Plates 31 and 32 are spaced in accordance with the thickness of plates 29 and 30 to slidably retain them therebetween.

The windage slide 29 is shown abutting the back or stop plate 31 and the elevation slide 30 is slidably engaging and disposed between the windage plate 29 and the outer end plate 32.

v The windage slide 29 is provided with a vertical slot 33 of a width generally corresponding to the width of the telescopic sight 8. The width of the windage slide 29 is substantially less than the width of the housing 9, as more clearly shown in FIG. 4. An adjusting captive screw 34 is threaded through a correspondingly threaded opening in the sidewall of the mounting housing 9. The end of screw 34 is secured to the windage slide 29. As most clearly shown in FIG. 4, the screw 34 is shown with a reduced inner end 35 which passes through an opening in slide 29 and tenninates in an enlarged head 36. Longitudinal movement of screw 34 therefore causes corresponding movement of the slide plate 29. Thus, rotation of the captive screw 34 results in the lateral movement of the windage slide 29 with a corresponding movement of the adjacent portion of the telescopic sight 8. This permits horizontal adjustment of the sight line of the telescopic sight 8.

The elevating slide plate 30 is generally similarly constructed with a slot 37 which extends in the horizontal direction and with a width essentially corresponding to the diameter of the telescopic sight 8. A captive screw 38 threads through a suitably tapped opening in the upper wall of the housing 9 with the innermost end thereof interconnected to the upper wall of the slide 30. Thus, rotation of the captive screw 38 results in a vertical positioning of the elevation slide 30 within the housing 9 with a'corresponding vertical movement of the adjacent portion of the telescopic sight 8. This, of course, pivots sight 8 within the opening 28 of the front mounting wall or plate 27 and permits accurate adjustment for elevation.

Thus, the archer will initially install the telescopic sight 8 with the clamp units 22 positioned to support the sight 8 at eye level. The sighting unit 4 is then horizontally adjusted with respect to the bow l for his particular style of shooting by positioning of the rods 5 and 6 in the respective to permit location of the telescopic sight 8 eyepiece within one or two inches of the eye. The sight 8 is repeatedly precisely located by the archer by merely proper location of the locating pad 26 adjacent the archers head. This provides for the repeatable precise drawback of the arrow and string 2. Windage and elevational compensation is made by adjustment of the captive screws, as previously discussed.

Applicants have found that the location of the telescopic sight 8 immediately adjacent the archers eye provides a much faster and more accurate aiming of the manually manipulated arrow. The locating extension also contributes'to the rapidity and accuracy of positioning of the bow as well as the proper and repeatable drawback of the string 2 to essentially the identical distance for successive shots. This permits consistent hitting of the target in essentially the same identical spot. Ap-

plicants have found that an initial archer with essentially no experience can, with a telescopic mounted sight of the present invention, rapidly and consistently hit within a given bullseye.

In FIGS. 8-11, an improved single piece support unit for a telescopic sight 39 is illustrated in accordance with the present invention. In this embodiment of the invention the telescopic sight 39 is similar to that described with respect to the first embodiment and is secured within a special mounting bracket 40 interconnected to a plate-like support member 41 which is releasably secured to a bow 42, of which only a fragmentary portion is shown. i

The plate-support member 41 is shown as a relatively thin metal plate which for example may be conveniently formed of stamped aluminum or the like. The member 41 is generally planar with a relatively wide mounting end adjacent the bow 42. The width or depth of the plate member decreases toward the shooter with the outermost substantially less than the mounting end. The deep part of member 41 is preferably apertured as at 43 to minimize the weight of the unit. The mounting end is attached to the outer face of the bow immediately above the hand grip portion and is offset with an angular connecting portion 44 to locate the principle plane of the member 41 just to the opposite side of the bow string 45. The offset end defines a flat clamping wall which is provided with a central slot 46 and a pair of elongated longitudinal mounting openings 47 and 48 to the opposite side of such slot. This wall is releasably interconnected to a separate mounting bracket 49 having projecting stud bolts and wing nuts 50 secured through the mounting openings 47 and 48. The mounting bracket 49 is also a flat plate-like member abutting the side of the bow 42 immediately above the hand-holding portion of the how 42 with a right angle locating flange 51 abutting out front face of the bow. Bracket 49 is clamped to the bow 42 by an encircling flexible strap 52, having a releasable interconnection shown as a conventional worm connecting screw unit 53 receiving a slotted or perforated coupling end of strap 52. The pair of mounting bolt units 50 extend laterally of the bow through the mounting openings which are horizontally elongated for limited positioning of the member 41. The plate 41 adjacent bow 42 is shown with an upper projection terminating ina V- shaped end 54 telescoped over the bow to further stabilize the mounting. The support member 41 extends rearwardly a sufficient distance to pass the head of the archer. An adjustable locating plate finger 55 is attached by a slotted connection 56 similar to the connection of the member 41 to plate 49. The finger 55 is located adjacent the arehers face with outer end bent toward his face to permit accurate and repeatable location of the bow 42. The face of finger 55 may be provided with a cushion cover 57.

The telescopic sight 39 is mounted to the outer end of the support member, 41 by the bracket 40. The sight 39 is mounted adjacent a reduced depth of the member 41 and in spaced relation to guide or finger 55 such that the eye piece 58 is immediately adjacent the archers eye.

Bracket 40 is provided with laterally extending apertured flanges 59 through which the telescopic sight 8 extends. The forward wall 59 is shown as a continuous wall having an opening through which the telescopic sight projects. Where a scope having an enlarged forward and rear lens units is to be employed, the forward wall should be formed as a two-piece unit for assembly, such as the illustrated back wall in FIGS. 8 and I 9. The back wall is formed with a pair of interconnected walls interconnected to each other by suitable bolts 60 or the like to clamp the sight 8 within the bracket 40. Elevational adjustment is permitted by a veru'eal arcuate slot 61 in the outer end of bracket 40 through which an attachment bolt and nut unit 62 extend to releasably attach the bracket 40 to member 41. The forward end of bracket 40 is secured by a nut and bolt unit 63 to define a fixed pivot connection. The scope 39 may, of course, include the known internal adjustment means, not shown, for accurate alignment.

In addition, the illustratedembodiment of the invention includes a bow string guide rod 64 interconnected to the outer face of the support member 41 and extending parallel to the support in slightly spaced relation thereto to define a bow string opening therebetween. The curved portion 44 of member 41 rod thus locates the rearwardly extending portion of the plate member 41 to the archers side of the bow string 45 to properly locate the sight 8 in alignment with the archers eye and guide opening, defined by rod 64, with the string 45. This provides a guide for the bow string 45 to permit accurate drawback of the string with repeatable location of the string upon each draw.

The second illustrated embodiment of the invention functions in the same general manner as the previous embodiment to locate the telescopic sight 8 immediately adjacent the archers eye for rapid and accurate aiming of the manually manipulated arrow, and furthermore to accurately locate the sight 8 of the bow 42 with respect to the archers eye for corresponding precise drawback of the arrow and arrow string 45. The mounting structure is such that the sight is firmly affixed to the bow without interfering with the movement of the archers hand or the convenient sighting of the unit while manually manipulating the unit.

The present invention provides an improved archery sighting apparatus for a manually drawn and held archery bow which can be operated with a minimum of skill to repeatably and accurately manually draw and release an arrow.

The sighting apparatus of the present invention is a relatively simple and inexpensive telescopic sight means and mountiug which can be employed for target, hunting and similar archery activities.
